6. TRI MIX

Utility: It is a bio consortium for management of root rot disease of mulberry. It involves the region specific isolates of Trichoderma harzianum.

Method of application:

One kg Tri-mix is mixed with 10 kg Neem oil cake and 30 kg FYM (for 80 plants). Roots of infected plants are exposed and the mixture is applied @ 500 g/plant (3 times/ year at an interval of 4 months) followed by irrigation. The technology reduces the disease severity up to 75- 80%.

7. NURSERY GUARD

Utility: For management of nursery diseases of mulberry

Method of application:

  • Mix 1 kg Nursery-Guard (Trichoderma pseudokoningii) with 60 kg Farm Yard Manure (sufficient for 2000 cuttings). Store the mixture under shade and keep it moistened by adding 10 - 12 litres of water for one week.
  • After one week, broadcast the mixture in to nursery beds @ 2 kg/m2 and mix well in the soil.
  • Soak the cuttings in Indofil M-45 (0.1 %) solution for 30 minutes and plant the cuttings in to treated beds followed by irrigation. 
  • For direct plantation of cuttings in to main field, apply ‘Nursery Guard’ mixture in pits @ 50 g/pit before plantation.

8. BIONEMA

Utility: To manage root knot disease of mulberry. This involves the application of ‘Bionema’ (Verticillium chlamydosporium) after mixing with FYM and neem oil cake in the ratio of 1:200:24 for control of root knot disease of mulberry.

Method of application:

  • Mix one kg Bionema with 200 kg FYM (for 1000 plants) and 24 kg neem oil cake, and store the mixture under the shade and keep moistened by sprinkling 30-32 liters of water for about one week.
  • Exposethe roots of infected plants by digging to a depth of 15 cm. Cut and remove bunches of knots on the roots and burn. 
  • Apply the prepared mixture @ 200 g/ plant around the exposed roots (3 times/ year at an interval of 4 months) during cultural operations/ fertilizer application followed by irrigation.
  • Bionema is a bio-nematicide, which is not having any toxic effect on both mulberry and silkworm.

9. RAKSHA

Utility: For control of soilborne disease of mulberry

This involves the application of both Indofil M-45 and biofungicide, ‘Raksha’ (Trichoderma harzianum). Prepare Raksha mixture by mixing of 1 kg Raksha with 50 kg FYM (for 100 plants), store the mixture under shade and keep moistened by adding 8-10 liters of water for over one week.

Method of application:

  • Uproot the diseased plants and burn.
  • Raksha does not have any toxic effect on both mulberry and silkworm.
